Thank you for taking the time to report this bug and helping to make Ubuntu better. Could you please add your '/etc/X11/xorg.conf' file and your '/var/log/Xorg.0.log' file as attachments to your bug report? Additionally after backing up your xorg.conf file it would be interesting to know what happens when you boot without one. Thanks in advance.
